Tu Duc gold 4 Tien ND (1848-83), Tu Duc Thong Bao/Tu Tien
Viet De, and Ten Virtues, around sun, KM535, Sch-380, XF45. Small
circular countermark on the obverse at seven o'clock. Crudely
struck, as normal for this issue, with noticeable re-cutting on
most of the devices. In addition to the usual flaws expected of
these poorly made issues, few other post striking imperfections are
noted. Extremely rare.
